SAUTO Practice Exam 1 — 20 Questions

Question 1

Which THREE of the following are essential components of a REST API request for a Cisco security product?

Accepted Answer

HTTP Method (e.g., GET, POST, PUT, DELETE).. REST requests consist of an HTTP method, a target URI, and necessary headers for authentication and content negotiation.

Answer

A predefined XML configuration file saved on the desktop.

Answer

A physical serial console cable connection.

Question 2

When parsing a complex JSON response from a Cisco Stealthwatch API call, you need to extract the value associated with a key nested deep within the hierarchy. Which Python approach is most idiomatic and robust for this task?

Accepted Answer

Load the response into a dictionary using json.loads() and access the keys using a chain of square brackets.. Using the built-in json module to load the string into a dictionary and accessing keys via standard dictionary lookups is the most robust method.

Answer

Convert the JSON to XML and use XPath to navigate the structure.

Answer

Use string slicing with find() to locate the key.

Answer

Use regex patterns to extract the value directly from the raw string.

Question 3

When parsing a JSON response from a Cisco Adaptive Security Appliance (ASA) REST API call using the Python requests library, you notice the data structure contains a list of objects under the key 'items'. Which Python expression correctly accesses the 'name' field of the first object in that list?

Accepted Answer

response.json()['items'][0]['name']. In Python, JSON objects are mapped to dictionaries, and arrays are mapped to lists. index 0 retrieves the first item.

Answer

response.json()['items'][1]['name']

Answer

response.json().items[0].name

Answer

response.json()['items'].get('name')[0]

Question 4

You are writing a Python script using the requests library to retrieve configuration from a Cisco Firepower Management Center (FMC). Which specific header must be included in your request to ensure that the server returns the response in JSON format?

Accepted Answer

Accept: application/json. The FMC API requires the 'Content-Type' or 'Accept' header to be set to 'application/json' to ensure proper data serialization and interpretation.

Answer

Content-Type: text/xml

Answer

Authorization: Bearer <token>

Answer

X-Auth-Token: <token>

Question 5

In a Cisco REST API implementation using Python, you receive a '429 Too Many Requests' error. What is the appropriate programmatic response?

Accepted Answer

Implement an exponential backoff strategy.. A 429 error indicates rate limiting; the client should implement exponential backoff to reduce request frequency.

Answer

Switch the request method from GET to POST.

Answer

Disable SSL verification for subsequent calls.

Answer

Increase the timeout duration of the request.

Question 6

Which TWO of the following are accurate regarding the structure and usage of YANG data models?

Accepted Answer

A 'leaf-list' is used to define an array of values of the same type.. YANG is a modeling language used to define data structures for network management protocols.

Answer

All YANG models are automatically applied to the device upon being uploaded.

Answer

YANG models must always be written in JSON format for the device to understand them.

Answer

YANG models are exclusively used for RESTCONF and cannot be used with NETCONF.

Question 7

Which THREE of the following are common benefits of using REST APIs for network automation?

Accepted Answer

Reduced configuration errors. Repeatability, scalability, and programmatically driven configurations are core benefits of APIs.

Answer

Automatic optimization of routing tables

Answer

Replacement of all network hardware

Question 8

You are debugging a NETCONF session to a Cisco device. The device sends an containing an . Which element inside the indicates the severity of the problem?

Accepted Answer

. The element in an structure specifies whether the error is 'error', 'warning', or 'info'.

Answer

<error-type>

Answer

<error-message>

Answer

<error-tag>

Question 9

Which TWO of the following are true regarding the 'requests' library's exception handling?

Accepted Answer

Timeout exceptions occur when the server takes too long to respond. Exceptions like Timeout and ConnectionError are critical for writing robust, production-ready automation scripts.

Answer

Exceptions are ignored by default

Answer

JSONDecodeError is an HTTP request error

Answer

ConnectionError is raised for successful connections

Question 10

Which TWO of the following are true regarding the use of the Python 'requests' library?

Accepted Answer

It can automatically serialize dictionaries to JSON via the json parameter.. The 'requests' library automatically handles connection pooling and provides simple methods for common HTTP verbs.

Answer

It only supports the synchronous execution model.

Answer

It requires manual management of connection pools.

Answer

It is only compatible with Python 2.7.

Question 11

When working with NETCONF, what is the role of the <edit-config> operation?

Accepted Answer

It changes the running configuration of the device.. The <edit-config> operation is used to modify the running configuration of a network device.

Answer

It retrieves the entire configuration from the device.

Answer

It deletes the entire configuration.

Answer

It creates a new session on the device.

Question 12

Which component of a REST API request is used to pass information about the requested resource in the URL?

Accepted Answer

Path parameters. Path parameters are embedded directly into the URL to identify specific resources.

Answer

Cookies

Answer

Headers

Answer

Body

Question 13

In a YANG model, which statement is used to define an operational constraint that must be true for the data to be valid?

Accepted Answer

must. The 'must' statement specifies a constraint expression that must evaluate to true for the data to be accepted.

Answer

mandatory

Answer

typedef

Answer

config

Question 14

While testing a REST API call in Postman for Cisco ISE, you receive a 403 Forbidden error. What is the most likely cause of this issue in the context of network programmability?

Accepted Answer

The API user account lacks the necessary roles or privileges to perform the requested operation.. A 403 error indicates that the server understands the request but refuses to authorize it, typically due to insufficient RBAC permissions for the API user account.

Answer

The authentication token has expired.

Answer

The server is currently undergoing maintenance.

Answer

The API endpoint URL is incorrectly formatted.

Question 15

In an HTTP request, what does the '201 Created' status code signify?

Accepted Answer

The resource was created successfully.. 201 Created is the standard HTTP status code indicating that a resource has been successfully created.

Answer

The request was accepted for processing but is not finished.

Answer

The request was received and processed successfully.

Answer

The request resulted in a temporary redirect.

Question 16

When using the Cisco IOS-XE RESTCONF API, which header is required to tell the server the format of the payload being sent?

Accepted Answer

Content-Type. The 'Content-Type' header specifies the media type of the request body (e.g., application/yang-data+json).

Answer

Cache-Control

Answer

Accept

Answer

Authorization

Question 17

When using NETCONF to manage a Cisco device, which message type is used to establish the initial session and exchange capability information?

Accepted Answer

. The element is the first message exchanged in a NETCONF session to identify capabilities.

Answer

<rpc>

Answer

<ok>

Answer

<rpc-reply>

Question 18

leaf

Answer

container

Question 19

In Postman, which feature allows you to automate a sequence of API calls and validate the output of each?

Accepted Answer

Answer

Environments

Answer

Mock Servers

Answer

Collections

Question 20

Which mechanism in YANG allows you to group multiple data nodes that are used in various parts of the model to reduce duplication?

Accepted Answer
